I used to do this very intentionally. In the past, I've found that taking notes is very valuable for me, but having notes seldom is.

When I was in school, I would write all my notes on a dry erase board and simply erase it when I had filled up the page. That was when I was studying things that were already known, though, so it was viable to, for reference material, just become skilled at referencing pre-existing reference material.

Now that I'm a professional and often working on something new or combining things in a new way, it's more often useful to me to generate new reference content for myself and especially for a different person who picks up the task on my day off.
